Linux 2.6 - man page for pcre_get_named_substring (linux section 3)

PCRE_GET_NAMED_SUBSTRING(3)					      PCRE_GET_NAMED_SUBSTRING(3)

NAME
       PCRE - Perl-compatible regular expressions

SYNOPSIS

       #include <pcre.h>

       int pcre_get_named_substring(const pcre *code,
	    const char *subject, int *ovector,
	    int stringcount, const char *stringname,
	    const char **stringptr);

DESCRIPTION

       This  is a convenience function for extracting a captured substring by name. The arguments
       are:

	 code	       Compiled pattern
	 subject       Subject that has been successfully matched
	 ovector       Offset vector that pcre_exec() used
	 stringcount   Value returned by pcre_exec()
	 stringname    Name of the required substring
	 stringptr     Where to put the string pointer

       The memory in which the substring is placed is obtained by calling pcre_malloc(). The con-
       venience  function  pcre_free_substring()  can  be  used  to  free it when it is no longer
       needed.	The  yield  of	the  function  is  the	length	of   the   extracted   substring,
       PCRE_ERROR_NOMEMORY  if sufficient memory could not be obtained, or PCRE_ERROR_NOSUBSTRING
       if the string name is invalid.

       There is a complete description of the PCRE native API in the pcreapi page and a  descrip-
       tion of the POSIX API in the pcreposix page.
